[0165] with an amine of general formula

[0166] wherein

[0167] R⁴ and R⁷ are as hereinbefore defined.

[0168] The reaction may be carried out in accordance with the conditions mentioned above for method (a).

[0169] If according to the invention a compound of general formula I is obtained which contains an amino, alkylamino or imino group, this may be converted by acylation or sulphonylation into a corresponding acyl or sulphonyl compound of general formula I or

[0170] if a compound of general formula I is obtained which contains an amino, alkylamino or imino group, this may be converted by alkylation or reductive alkylation into a corresponding alkyl compound of general formula I or

[0171] if a compound of general formula I is obtained which contains a carboxy group, this may be converted by esterification into a corresponding ester of general formula I or

[0174] The subsequent alkylation is optionally carried out in a solvent or mixture of solvents such as methylene chloride, dimethylformamide, benzene, toluene, chlorobenzene, tetrahydrofuran, benzene/tetrahydrofuran or dioxane with an alkylating agent such as a corresponding halide or sulphonic acid ester, e.g. with methyl iodide, ethyl bromide, dimethylsulphate or benzyl chloride, optionally in the presence of a tertiary organic base or in the presence of an inorganic base, expediently at temperatures between 0 and 150° C., preferably at temperatures between 0 and 100° C.

However, the methylation is preferably carried out in the presence of formic acid as reducing agent at elevated temperatures, e.g. at temperatures between 60 and 120° C.

[0176] The subsequent esterification is optionally carried out in a solvent or mixture of solvents such as methylene chloride, dimethylformamide, benzene, toluene, chlorobenzene, tetrahydrofuran, benzene/tetrahydrofuran or dioxane or most advantageously in a corresponding alcohol optionally in the presence of an acid such as hydrochloric acid or in the presence of a dehydrating agent, e.g. in the presence of isobutyl chloroformate, thionyl chloride, trimethylchlorosilane, sulphuric acid, methanesulphonic acid, p-toluenesulphonic acid, phosphorus trichloride, phosphorus pentoxide, N,N′-dicyclohexylcarbodiimide, N,N′-dicyclohexylcarbodiimide/N-hydroxysuccinimide or 1-hydroxy-benztriazole and optionally also in the presence of 4-dimethylamino-pyridine, N,N′-carbonyldiimidazole or triphenylphosphine/carbon tetrachloride, conveniently at temperatures between 0 and 150° C., preferably at temperatures between 0 and 80° C.

[0177] The subsequent amidation is carried out by reacting a corresponding reactive carboxylic acid derivative with a corresponding amine, optionally in a solvent or mixture of solvents such as methylene chloride, dimethylformamide, benzene, toluene, chlorobenzene, tetrahydrofuran, benzene/tetrahydrofuran or dioxane, while the amine used may act as solvent at the same time, optionally in the presence of a tertiary organic base or in the presence of an inorganic base or with a corresponding carboxylic acid in the presence of a dehydrating agent, e.g. in the presence of isobutyl chloroformate, thionyl chloride, trimethylchlorosilane, sulphuric acid, methanesulphonic acid, p-toluenesulphonic acid, phosphorus trichloride, phosphorus pentoxide, O-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium-tetrafluoroborate, N,N′-dicyclohexylcarbodiimide, N,N′-dicyclohexylcarbodiimide/N-hydroxysuccinimide or 1-hydroxy-benztriazole and optionally also in the presence of 4-dimethylamino-pyridine, N,N′-carbonyldiimidazole or triphenylphosphine/carbon tetrachloride, conveniently at temperatures between 0 and 150° C., preferably at temperatures between 0 and 80° C.

[0178] In the reactions described hereinbefore, any reactive groups present such as hydroxy, carboxy, amino, alkylamino or imino groups may be protected during the reaction by conventional protecting groups which are cleaved again after the reaction.

[0179] For example, a protecting group for a hydroxy group may be a trimethylsilyl, tert.butyl-dimethylsilyl, acetyl, benzoyl, methyl, ethyl, tert.butyl, trityl, benzyl or tetrahydropyranyl group,

[0180] a protecting group for a carboxyl group may be a trimethylsilyl, methyl, ethyl, tert.butyl, benzyl or tetrahydropyranyl group and

[0181] protecting groups for an amino, alkylamino or imino group may be a formyl, acetyl, trifluoroacetyl, ethoxycarbonyl, tert.butoxycarbonyl, benzyloxycarbonyl, benzyl, methoxy-benzyl or 2,4-dimethoxybenzyl group and additionally, for the amino group, a phthalyl group.

[0182] Any protecting group used is optionally subsequently cleaved for example by hydrolysis in an aqueous solvent, e.g. in water, isopropanol/water, acetic acid/water, tetrahydrofuran/water or dioxane/water, in the presence of an acid such as trifluoroacetic acid, hydrochloric acid or sulphuric acid or in the presence of an alkali metal base such as sodium hydroxide or potassium hydroxide or aprotically, e.g. in the presence of iodotrimethylsilane, at temperatures between 0 and 120° C., preferably at temperatures between 10 and 100° C. However, a silyl group may also be cleaved using tetrabutylammonium fluoride as described hereinbefore.

[0183] However, a benzyl, methoxybenzyl or benzyloxycarbonyl group is cleaved, for example hydrogenolytically, e.g. with hydrogen in the presence of a catalyst such as palladium/charcoal in a suitable solvent such as methanol, ethanol, ethyl acetate or glacial acetic acid, optionally with the addition of an acid such as hydrochloric acid at temperatures between 0 and 100° C., but preferably at temperatures between 20 and 60° C., and at a hydrogen pressure of 1 to 7 bar, but preferably 3 to 5 bar. A 2,4-dimethoxybenzyl group, however, is preferably cleaved in trifluoroacetic acid in the presence of anisole.

[0184] A tert.butyl or tert.butyloxycarbonyl group is preferably cleaved by treating with an acid such as trifluoroacetic acid or hydrochloric acid or by treating with iodotrimethylsilane, optionally using a solvent such as methylene chloride, dioxane, methanol or diethylether.

[0185] A trifluoroacetyl group is preferably cleaved by treating with an acid such as hydrochloric acid, optionally in the presence of a solvent such as acetic acid at temperatures between 50 and 120° C. or by treating with sodium hydroxide solution, optionally in the presence of a solvent such as tetrahydrofuran at temperatures between 0 and 50° C.

[0186] A phthalyl group is preferably cleaved in the presence of hydrazine or a primary amine such as methylamine, ethylamine or n-butylamine in a solvent such as methanol, ethanol, isopropanol, toluene/water or dioxane at temperatures between 20 and 50° C.

[0187] Moreover, the compounds of general formula I obtained may be resolved into their enantiomers and/or diastereomers, as mentioned hereinbefore. Thus, for example, cis/trans mixtures may be resolved into their cis and trans isomers, and compounds with at least one optically active carbon atom may be separated into their enantiomers.

[0188] Thus, for example, the cis/trans mixtures obtained may be resolved by chromatography into the cis and trans isomers thereof, the compounds of general formula I obtained which occur as racemates may be separated by methods known per se (cf. Allinger N. L. and Eliel E. L. in “Topics in Stereochemistry”, Vol. 6, Wiley Interscience, 1971) into their optical antipodes and compounds of general formula I with at least 2 asymmetric carbon atoms may be resolved into their diastereomers on the basis of their physical-chemical differences using methods known per se, e.g. by chromatography and/or fractional crystallisation, and, if these compounds are obtained in racemic form, they may subsequently be resolved into the enantiomers as mentioned above.

[0189] The enantiomers are preferably separated by column separation on chiral phases or by recrystallisation from an optically active solvent or by reacting with an optically active substance which forms salts or derivatives such as e.g. esters or amides with the racemic compound, particularly acids and the activated derivatives or alcohols thereof, and separating the diastereomeric mixture of salts or derivatives thus obtained, e.g. on the basis of their differences in solubility, whilst the free antipodes may be released from the pure diastereomeric salts or derivatives by the action of suitable agents. Optically active acids in common use are e.g. the D- and L-forms of tartaric acid or dibenzoyltartaric acid, di-o-tolyltartaric acid, malic acid, mandelic acid, camphorsulphonic acid, glutamic acid, aspartic acid or quinic acid. An optically active alcohol may be for example (+) or (−)-menthol and an optically active acyl group in amides, for example, may be a (+)-or (−)-menthyloxycarbonyl.

[0190] Furthermore, the compounds of formula I may be converted into the salts thereof, particularly for pharmaceutical use into the physiologically acceptable salts with inorganic or organic acids. Acids which may be used for this purpose include for example hydrochloric acid, hydrobromic acid, sulphuric acid, phosphoric acid, fumaric acid, succinic acid, lactic acid, citric acid, tartaric acid or maleic acid.

[0191] Moreover, if the new compounds of formula I thus obtained contain an acidic group such as a carboxy group, they may subsequently, if desired, be converted into the salts thereof with inorganic or organic bases, particularly for pharmaceutical use into the physiologically acceptable salts thereof. Suitable bases for this purpose include for example sodium hydroxide, potassium hydroxide, arginine, cyclohexylamine, etha-nolamine, diethanolamine and triethanolamine.

[0192] The compounds of general formulae II to V used as starting materials are either known from the literature or may be obtained by methods known from the literature or are described in the Examples.

[0193] A compound of general formula II is obtained, for example, by reacting a compound of general formula

[0194] wherein R¹ to R³ are as hereinbefore defined and Z¹ denotes a carboxy group or a reactive derivative of a carboxy group, with an amine of general formula

[0195] wherein R⁴ to R⁷ are as hereinbefore defined and Z² denotes a protecting group for a carboxy group, and subsequently cleaving the protecting group.

[0196] The amines of general formula III wherein R⁶ denotes a heteroaryl-aryl group or a heteroaryl-aryl-C₁₋₆-alkyl group, may be prepared, for example, by synthesising the heteroaromatic ring from suitably substituted aryl or aryl-C₁₋₆-alkyl educts, possibly by reactions of condensation with suitable dicarbonyl compounds.

[0197] The biphenyl-2-carboxylic acids according to general formula IV are known from the literature or may be prepared by methods known from the literature from corresponding biphenyl educts.

[0198] The 3-amino-benzoic acid amides according to general formula VI are also known from the literature or may easily be prepared from optionally substituted 3-aminobenzoic acids by reacting with the corresponding amines.

[0199] As already mentioned hereinbefore, the compounds of general formula I and the physiologically acceptable salts thereof have valuable pharmacological properties. In particular, they are valuable inhibitors of the microsomal triglyceride-transfer protein (MTP) and are therefore suitable for lowering the plasma levels of the atherogenic lip oproteins.

[0200] For example, the compounds according to the invention were investigated for their biological effects as follows:

[0201] Inhibitors of MTP were identified by a cell-free MTP activity test. Solubilised liver microsomes from various species (e.g. rat, pig) can be used as the MTP source. To prepare the donor and acceptor vesicles, lipids dissolved in organic solvents were mixed in a suitable ratio and applied to the wall of glass container in a thin layer by blowing the solvent in a nitrogen current. The solution used to prepare donor vesicles contained 400 μM of phosphatidyl choline, 75 μM of cardiolipin and 10 μM of [¹⁴C]-triolein (68.8 μCi/mg). To prepare the acceptor vesicles, a solution of 1.2 mM of phosphatidyl choline, 5 μM of triolein and 15 μM of [³H]-dipalmitoyl-phosphatidyl choline (108 mCi/mg) was used. Vesicles are produced by wetting the dried lipids with test buffer and subsequently treating with ultrasound. Vesicle populations of uniform size were obtained by gel filtration of the ultrasound-treated lipids. The MTP activity test contains donor vesicles, acceptor vesicles as well as the MTP source in test buffer. Substances were added from concentrated DMSO-containing stock solutions, the final concentration of DMSO in the test was 0.1%. The reaction was started by the addition of MTP. After a corresponding incubation time the transfer process was stopped by the addition of 500 μl of a SOURCE 30Q anion exchanger suspension (Pharmacia Biotech). The mixture was shaken for 5 minutes and the donor vesicles bound to the anion exchanger material were separated off by centrifuging. The radioactivity of [3H] and [¹⁴C] in the supernatant was determined by liquid scintillation measurement and from this the recovery of the acceptor vesicles and the triglyceride transfer speed was calculated. The compounds of general formula I exhibit IC₅₀ values≦100μM in the test described.

[0202] In view of the abovementioned biological properties the compounds of general formula I and the physiologically acceptable salts thereof are particularly suitable for lowering the plasma concentration of atherogenic apolipoprotein B (apoB)-containing lipoproteins such as chylomicrons and/or very low density lipoproteins (VLDL) as well as the residues thereof such as low density lipoproteins (LDL) and/or lipoprotein(a) (Lp(a)), for treating hyperlipidaemias, for preventing and treating atherosclerosis and the clinical sequelae thereof, and for preventing and treating related disorders such as diabetes mellitus, adiposity and pancreatitis, oral administration being preferred.

[0203] The daily dose needed to achieve such an effect is between 0.5 and 500 mg, expediently between 1 and 350 mg, but preferably between 5 and 200 mg, in adults.

[0204] For this purpose, the compounds of formula I prepared according to the invention, optionally combined with other active substances such as other lipid-lowering agents, for example HMG-CoA-reductase-inhibitors, cholesterol biosynthesis inhibitors such as squalene synthase inhibitors and squalene cyclase inhibitors, bile acid-binding resins, fibrates, cholesterol resorption inhibitors, niacin, probucol, CETP inhibitors and ACAT inhibitors together with one or more inert conventional carriers and/or diluents, e.g. with corn starch, lactose, glucose, microcrystalline cellulose, magnesium stearate, polyvinylpyrrolidone, citric acid, tartaric acid, water, water/ethanol, water/glycerol, water/sorbitol, water/polyethyleneglycol, propylene glycol, stearyl alcohol, carb-oxymethylcellulose or fatty substances such as hard fat or suitable mixtures thereof in conventional galenic preparations such as plain or coated tablets, capsules, powders, suspensions or suppositories.
